Chapter 69: Exclusive to Erwin, the sound transmission spell can be used!

At the podium, Flitwick didn't care that the class had become a little noisy because students were running to Erwin for advice.

Instead, he looked at Erwin with relief.

Look, what a good student.

What a worry-free student! He has strong abilities and never forgets to help his classmates.

Such a person should come to Ravenclaw.

Although it is already very good that Ravenclaw has Hermione now.

But for good students, who would think it’s too much?

Once again, Flitwick was sure that the Sorting Hat must have short-circuited.

That's why a Ravenclaw like this was sorted into Slytherin.

Wouldn't such a simple student suffer in an environment like Slytherin?

Flitwick once again thought of going to see Dumbledore.

Erwin taught these little wizards.

While thinking about the sound transmission spell in his mind.

This thing cannot be used by other people, mainly because of the magic power that comes from the same source.

Even if they are twins, their magic powers are different.

No matter how insignificant the difference is, it is still a difference.

However, this limitation applies to Elvin.

It doesn't seem to be a limitation.

I mentioned it before.

Erwin's Purple Lotus Mark is a system product, so it has some special functions.

Take the Dark Mark, for example.

The Dark Mark has three functions.

The first one is to allow the Death Eaters to turn into a black ball and fly around.

This is a customized feature for faction leaders.

The second function is that Voldemort can sense the location of the Death Eaters through the Dark Mark.

The third function is that the Death Eaters can contact Voldemort through the Dark Mark. This contact is of course not through voice or video calls, but when they activate the Dark Mark, Voldemort can sense it!

To put it simply, cough cough cough, your friend is online.

Yes, just online.

Erwin's Purple Lotus Mark has all three functions.

However, compared with the Dark Mark, Erwin's Purple Lotus Mark has an additional major function.

That is, Erwin can inject magic power into the Purple Lotus Mark.

This function was added by the system. Its purpose is to allow Alvin to directly control the life and death of people marked with the purple lotus through this magic power.

If anyone has any bad intentions, Alvin can directly detonate this magic power.

Just like Old Tom, he was able to enter Diagon Alley because of the magic of Erwin on his arm, which allowed him to leave the ranks of Muggles and join the ranks of Squibs.

Although he cannot use magic, he is immune to the Muggle-Repelling Spell because of the magic left by Erwin.

And it is precisely because of the existence of this function.

Let Alvin discover that he can really use this voice transmission spell.

They share the same origin, and all the magic power comes from him.

Aren't they of the same origin?

The most important thing is that this ability cannot be copied by others.

The magic will dissipate.

However, the Purple Lotus Mark of Erwin's system modification can lock the magic power inside the Purple Lotus Mark.

Even if Voldemort knew the principle, he couldn't do it!

It can be said that this voice transmission spell was completely customized for Erwin.

Still, the theory holds.

Whether it can be successful or not.

Alvin felt that he still needed to find a suitable test subject.

Erwin is a steady guy.

As the saying goes, true knowledge comes from experiments.

The launch of every new product requires a lot of refinement.

But who should we find as the test subject?

Erwin was in a dilemma.

A Slytherin student?

Erwin had just established himself as a selfless prefect and had created a purple lotus mark.

No matter how you look at it, it doesn't seem very decent.

Especially this thing, which is very famous in the wizarding world, it would be strange if you didn't know the name of the Dark Mark.

This can easily affect Erwin's personality.

The little snakes are small, but they are not stupid.

His only follower Patton?

It seems a bit inappropriate.

Patton's plan for pure blood after he got involved with Irwin.

What if I die while playing?

That's not worth it.

In other words, Patton is still useful!

I can die, but I can’t die now!

The most important thing is that the experiment is risky, so Alvin cannot choose the little wizard.

If he really killed one of them, he would really have to go to Azkaban.

Who else?

Without being able to leave Hogwarts!

Hagrid?

No, that stupid guy is a supplier and he can’t die!

at this time.

Erwin's eyes suddenly lit up.

It seems that no one has said that the test subjects must be humans, right?

Erwin suddenly felt his thoughts become clearer.

It seems necessary to take a trip to the forbidden forest.

Giant spiders and centaurs, aren’t these the best experimental materials?

I wouldn't feel bad if he died, and he has no use value.

Alvin has determined his experimental goals, so it seems he needs to take a walk in the Forbidden Forest.

I guess those things in the forbidden forest are very welcome to Elvin.

After all, Erwin also has the ability to be friendly with magical animals.

He hasn't tried it yet.

After Charms comes Herbology.

Nothing extra happened though.

The Herbology class with Ravenclaw wasn't exciting at all.

The whole afternoon class was a bit boring.

Gotta say it, Erwin really missed Gryffindor a little.

Without Gryffindor, it seems like there would be less fun.

In the auditorium at night.

After dinner, Erwin was called to Professor McGonagall's office.

"Sit down, Erwin!"

Erwin nodded.

Without any hesitation, he sat down on the chair.

"Professor McGonagall! Are you looking for me about morning and evening study?"

Professor McGonagall nodded. "Yes, the professors are very supportive. However, there is a problem. If we have self-study classes, the professors will be too busy!"

Erwin was delighted.

What he was waiting for was Professor McGonagall to ask him.

Erwin said, "Professor McGonagall! This is what I think! Professors are very tired after a day of teaching! And they need to prepare lessons, study on their own, and to put it bluntly, study on their own! I think it is entirely possible to let the class leaders take charge of guidance, and lower grade students can ask senior students, or communicate with classmates to promote learning! In fact, to put it bluntly! Self-study is used to organize what has been learned that day! The role of professors is not very big. After all, we can't ask professors to teach new content, right? In this way, students can't absorb so much knowledge!"

Professor McGonagall nodded. "I see! Now I understand what you said! It's a great idea! I'm really curious about what's going on in your head! If that's the case, then we can implement the self-study program! Today is Thursday, so let's start trying next week!"

Erwin's mouth curled up.

It became.

The road to gaining points has become smooth.

Young wizards, are you going to lose one hour of rest time, two hours of rest time, or no rest time from now on?
